As first caught by Mediaite, using his verified Twitter account, CNN anchor and correspondent Bill Weir lashed out at Fox News as “willfully ignorant fucksticks” over a tweet from the network’s Website Fox Nation about the “climate” not cooperating with Al Gore.

CNN is a cable news network that frequently lectures others on civility. A politician CNN considers uncivil is frequently brought on the air for an intense grilling. CNN has also been critical of Fox News anchors they deem uncivil.

According to Mediaite, CNN has not yet responded to Weir publicly lashing out at Fox News.
